  • A Detailed Guide on Grading of Aggregates.

    When the coarse aggregates are packed to make the concrete, the voids formed within the mass must be filled by some finer material. Sand is used for this purpose. But, there will be voids left between the sand grains too. These are filled with the cement particles. In this way, the resulting concrete mass is a void-less or dense mass.

    A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem
